O-Ring (2pk) GM LS Oil Pump

The MOROSO O-Ring (2pk) GM LS Oil Pump is a vital maintenance component for LS engine builders and high-performance mechanics working on General Motors' LS platform. These sealing rings are designed to prevent oil bypass and ensure proper pump function, making them essential during engine assembly or rebuilds.

Manufactured from elastomeric polymer, these O-rings maintain their integrity across a range of temperatures and pressures typical of both street and track LS engines. Their geometry creates a dynamic seal around the oil pump's rotating shafts, which is critical for preventing cavitation and oil starvation.

Ideal for LS engine swappers, rebuild shops, and tuners, these O-rings are compatible with various LS displacement variants, including LS1, LS2, LS3, LS9, and truck blocks. Having quality replacement O-rings on hand helps eliminate downtime and protects your investment in high-performance engines.
